Tag Cloud for ftp blogger blogs

In the sidebar section for Blogger template, include:

The following is a modified version of tag cloud source I found.



define('PREFIX', 'labels/'); // for url
define('SEARCH_DIR', '/home/username/www/labels'); // server location of labels subdirectory

define('THIS_FILE', 'labels.php'); // name of labels file (this file)

if(file_exists(SEARCH_DIR.'_cloud_include_cache.php') &&
filemtime(SEARCH_DIR.'_cloud_include_cache.php')>(time()-(60*60)))
{
echo file_get_contents(SEARCH_DIR.'_cloud_include_cache.php');
}
else
{
build_cloud();
}

/**
* build_cloud builds a tag cloud from the labels files.
* It actually uses labels file size to determine font size... which does
* not necessarily coincide with number of posts for a given label.
*
* smallest file is assigned 100% font-size. largest file - 200%
* everything else is proportional in between.

function build_cloud()
{
$output = '';
$files = array();
$dir = opendir(SEARCH_DIR);
$low_end=PHP_INT_MAX;
$high_end=0;
while($file = readdir($dir))
if($file != '.' && $file != '..' && $file != THIS_FILE && $file != CACHE_FILE)

$files[$file] = filesize(SEARCH_DIR."/".$file);
$low_end = min($low_end, $files[$file]);

ksort($files);
foreach($files as $name=>$size)
{
$output .= "

}
echo $output;

  1. Thanks, exactly what I was looking for. However I needed to change

    str_replace('.php','',$name)

    to

    str_replace('.html','',$name)

    in order to strip the file name extension.
